Question

Function d gives the distance of a boat from the dock t seconds after leaving the dock. Distance is measured in meters.
Here is a graph that represents d.
80
60
40
20 40 60 80 100 120 140 160 180
time (seconds)
Select all statements in function notation that represent the situation.
Od(30) = d (70)
Id(10) = 20
Od (90) < d (160)
Id(t) = 10 when t is 20
Od (0) = 0
Id(0) = 170
Id(170) = 0

Answer 1

Answer:

:)

Step-by-step explanation:

d(0)=0

d(0)=170

d(90)<d(160)

d(t)=10 when t is 20

Answer 2

The true statements from the function are:

• d(30) = d(70)
• d(10) = 20
• d(0)=0
• d(170) = 0.

Functions can be represented as graphs and equations.

The equation of the graph is represented as:

$y = d(t)$

From the graph, we have the following parameters

$d(30) =d(70) = 40$

$d(10) = 20$

$d(0) = d(170) = 0$

Hence, the true options are (a), (b), (e) and (h)
